Abstract
The invention discloses a tower beam consolidation cable-stayed bridge 0# block support cast-in-place and movable suspended scaffolding suspension pouring combined construction method and belongs to the field of bridge construction. Support method construction is adopted in all 0# block cast-in-place box beam construction in the prior art, security risks existing in actual application are large, construction quality is difficult to control, construction progress is slow, cost is high, and manpower and machine utilization efficiency is low. In order to reduce construction security risks and construction cost, 0# block construction is divided into construction of two parts, wherein conventional support method construction is adopted in the first part (TO-1 segment), movable suspended scaffolding construction is adopted in the second part (TO-2 segment), and a movable suspended scaffolding to be used for construction of a 1# block and follow-up blocks is installed and constructed before the former half segment (the second part of a 0# block) is to be constructed, in this way, material input of about half of a support can be saved, cost is saved, construction is accelerated, the safety factor is improved, and the tower beam consolidation cable-stayed bridge 0# block support cast-in-place and movable suspended scaffolding suspension pouring combined construction method is achieved.
Description
Technical field
Type of the present invention relates to the construction method that a kind of cable-stayed bridge with tower beam consolidation 0# piece support cast-in-place combines with Hanging Basket cantilever.
Background technology
In the work progress of large-scale Tower Column of A Cable Stayed Bridge beam consolidation section 0# piece, in especially large-scale high trestle construction of cast-in-situ box-beam, there is larger safety, hidden danger of quality, material has high input, and construction cost is high.
0# piece construction of cast-in-situ box-beam all adopted construction with brackets in the past, and the security risk existing is in actual applications large, quality control on construction difficulty, and progress is slow, and cost is high, and personnel's machinery service efficiency reduces.Therefore for reducing construction safety risk, reduce construction cost, hereby the construction of 0# piece section is divided into two part constructions, Part I (TO-1 section) adopts large-scale superelevation steel pipe support method construction, steel pipe support is supported on king-tower lower king-post strut root, Part II (TO-2 section) adopts cradle construction, is about to Hanging Basket half sections (being the Part II (TO-2 section) of 0# piece) installation in advance, construction for 1# piece and the construction of subsequent block section.Can reduce like this input of approximately 1/2 timbering material, save cost, accelerating construction progress, safety assurance coefficient is improved, and forms the construction method that a kind of brand-new tower beam consolidation section 0# piece support cast-in-place combines with Hanging Basket cantilever for this reason.

The feature of type of the present invention is: construction method technique is simple, structure stress is clear and definite, easy to assembly, safe and reliable, make to construct more convenient, quick, reliable, break the inertial thinking theory that conventional 0# piece must adopt construction with brackets, saved a large amount of supporting structure materials, reached safety, efficient, quick, saving target.
Description process operations step is:
First carry out the assembling construction of concrete beam support;
Further, carry out that support is linear, the adjustment of absolute altitude;
Further, carry out the part 0# block concrete construction of crossbeam and first construction;
Further, after stretch-draw transverse prestress bundle, in the 0# section of having built, carry out the assembling construction of Hanging Basket;
Further, carry out that Hanging Basket is linear, the adjustment of absolute altitude;
Further, install after accurate adjustment, i.e. lockable Hanging Basket fastening devices, guarantees that safety is firmly cemented on the first demisection beam of 0# piece body;
Further, carry out reinforcing bar, prestressing tendon installation;
Further, carry out 0# piece Part II concrete pouring construction;
Further, concrete strength meets after standard-required, removes Hanging Basket locking device, carries out the reach of Hanging Basket, and assembled Hanging Basket residue system, starts subsequently the construction of other standard beam sections body;
Further, until cradle construction all completes, bridge closes up.
The construction method that described a kind of cable-stayed bridge with tower beam consolidation 0# piece support cast-in-place combines with Hanging Basket cantilever, it is characterized in that: in described Cable-stayed Bridge Pylon construction, tower beam consolidation 0# piece girder is divided into two part constructions, first half (TO-1 section) adopts construction with brackets, latter half (TO-2 section) adopts cradle cantilever construction, the i.e. assembled and anchored platform as Hanging Basket at completed 0# piece first half beam body, utilize subsequently the support system of Hanging Basket as box beam concrete structure, carry out the structure construction of 0# piece latter half beam body.
The construction method of utilizing the tower beam consolidation 0# piece support cast-in-place of type of the present invention to combine with Hanging Basket cantilever, tool has the following advantages:
One, adopt support to combine with Hanging Basket and carry out the construction of 0# piece sections, significantly reduced the consumption of 0# piece high trestle system, shortened construction period, improved safety factor, reduced security risk, and for follow-up Hanging Basket carries out the standard segmental construction condition of providing convenience, and make complicated procedures of forming have more simplification.
Two,, entirety has been accelerated 12% construction speed.
Three, reduced approximately 16% construction cost.
